C# - The Input Stream Is Not A Valid Binary Format / Cannot Use Binary As The Length Is Around 15.000

Feb 3, 2011

I have a problem with deserializing in C#/ASP.NET, which gives the exact error:

The input stream is not a valid binary format. The starting contents (in bytes) are: 41-41-45-41-41-41-44-2F-2F-2F-2F-2F-41-51-41-41-41 ...

What I am trying to do

I have a structure with 3 classes. I have a class A which is a base class, and then class B and C which are derived from A.

I am trying to store random types of B and C in the database using LINQ to SQL, in a column with the type VARCHAR(MAX).

I cannot use BINARY as the length is around 15.000.

My code...

[code]...

So the error happends when the first Deserialize method is run, with the above error.

Sending A Binary Stream To The Clients Browser?

Aug 1, 2010

I was wondering if there is any difference in performance (or any other important factor) between a file sent to the browser from our server by this method :

For i = 1 To fileSize chunk
If Not Response.IsClientConnected Then Exit For
Response.BinaryWrite stream.Read(chunk)
Response.Flush
Next
VS

the old plain file access method that the IIS comes with.

We are working on a file manager handler for security reasons and would like to know what is the performance hit.

Send Binary Stream To Browser And Then Update The Page?

Mar 15, 2011

I have an ASP.NET page with a text status and a button to export an Excel file. When the user clicks the button, I want to generate the file on the fly and return it to the client as binary stream. Then I want to change the text status to show success/failure.

So far I can generate and send the file no problem, but obviously the statuses don't get displayed, since the server response was used to send the file and not a new updated page with the new status.

I'm not sure what's the cleanest way to approach this. I can think of something but is it the best way:

User clicks on button. File is generated and saved as a stream in the session. Statuses are updated and the page with the new statuses is returned to the client. A piece of Javascript on the page opens a 3rd party page which retrieves the saved stream from the session.

Forms Data Controls :: Deserialing Binary Stream And Loading To Chart?

Nov 1, 2010

I have a MS Chart Control and I'm trying to serialize the chart to view state. When teh page postbacks, I wnat to de-serialize the chart from ViewState, then load it back to the Chart's serializer. When the Chart1.Serializer.Load is called, I get an error message stating Data at the root level is invalid, line 1 position 1.

So here's what I have:

Chart1.Serializer.Format = System.Web.UI.DataVisualization.Charting.SerializationFormat.Binary;
Chart1.Serializer.Content = System.Web.UI.DataVisualization.Charting.SerializationContents.All;
Chart1.Serializer.Save(myStream);
ViewState["myStream"] = myStream.ToArray();
On postback, when the routine is called:
System.Byte [] byters;
System.IO.MemoryStream myStream = new System.IO.MemoryStream();
if (ViewState["myStream"] != null)
{
byters = (System.Byte[])ViewState["myStream"];
myStream.Write(byters,0,byters.Length);
myStream.Position = 0;
Chart1.Serializer.Load(myStream); // this line throws a XmlException - data at the root level is invalid. line 1 , position 1.
}

The length of the stream was 15,518 and capacity was 16,384 when it made the save. On postback, both capacity and length became 15,518.

HTTP - Stream.Write Fails On Server But Works On Dev Machine?

Jan 23, 2011

problem with Stream.Write() where it works under a dev (Windows 7) environment but fails under a server environment (Windows 2008 R2 Enterprise)?

I'm basically working with some third party code which reads from a FileStream and writing to an Http request, nothing unusual and it's doing the following things:

Ensuring that Response.KeepAlive is false (was originally true but worked W7 and not W2K8 so tried false but it doesn't );
Ensuring that the Write includes the length of the bytes to write;
Ensuring that I Flush the stream afterwards;

The error that I encounter is the rather vague 'The request was aborted: The request was canceled.' with InnerException of 'Cannot close stream until all bytes are written.'. Now, my code works perfectly under Windows 7 so I still suspect that something is actively blocking this writing although I am not sure what, how and where.

One other possibility I wondered about was whether the encoding might be different under Windows Server 2008 R2 as opposed to Windows 7?

Here's a code snippet from the relevant method (a bit convoluted but, disclaimer, I didn't write it :-):

string boundary = string.Concat("-------------------------", DateTime.Now.Ticks.ToString("x", CultureInfo.InvariantCulture));
byte[] boundaryBytes = System.Text.Encoding.UTF8.GetBytes(string.Concat("
--", boundary, "
"));........
